Serial No. 774,674.

To allwhomit may concern: centrally upon a shaft N journaled in the Be it known that I, EosoN G. GOODRICK, a bearings K. said cable thence passing upcitizen of the United States, residing at ward and adapted to extend over a pulley Brush, in the county of Morgan and State and have the usual drill, not shown, attached 60 5 of Colorado, have invented certain new and thereto. The ends of the beams L, which useful Improvements in Well-Drilling Maare opposite those carrying the shaft K, chines; and I do hereby declare the follow carry a stub shaft journaled in suitable ing to be a full, clear, and exact description hearings in the beams and an eccentrically of the invention, such as will enable others mounted gear wheel 0' is fixed to the shaft 0 skilled in the art to which it appertains to t) and. has its teeth in engagement with the make and use the same, reference being had teeth of an eccentric gear wheel O which is to the accompanying drawings, and to the fixed to a shaft 0 carried in the bearings 0 letters and figures of reference marked which are fastened underneath the beams of thereon, which form a part of this specificathe frame A. 70 tion. Fastencd to the under surface of the This invention relates to new and useful frame are the bearing blocks 1, one of improvements in well drilling apparatus and which has journaled therein a rocking cam comprises a simple and efficient device of member R, a detail of which is shown in this nature having various details of con- Figs. 3 and 4t, from which member R an arm 75 struction and combinations and arrange R projects and which is pivotally connected ments of parts which will be hereinafter to a rod it which in turn is pivotally confully described. shown in the accompanying nectcd with the short arm of a lever R, pivdrawings and then specifically defined in the oted on a pin R". A shaft J is journaled at appended claims. one end in a cam bearing R, as shown clearly so My invention is illustrated in the accomin Figs. 3 and 4- of the drawings, and its panying drawings, in which zother end in a bearing l at the opposite side Figure l. is a side elevation of the appara of the frame, and a pinion R is fixed to the tus. Fig. 9 is a top plan view, partially in shaft J and is in mesh with a gear wheel 0 section. Fig. 3 is a detail view of an ecccnfastened to the shaft 0. A frictionally 30 trio bearing shifting device, and Fig. 4.- is a driven pulley it is also fastened to the shaft side elevation of the shifting means illus- J and is adapted to frictionally engage the trated in Fig. 3. groi'ived driving wheel E to receive power Reference now being had to the details of therefrom. the drawings by letter, A designates the A. shaft 9 is journaled at one end in a 5 frame of the apparatus having upright boxing S upon one side of the frame and in beams B and B, the upper portions of a similar boxing 8 upon the opposite side, which are broken away. Mounted in the the said boxing S having a cam bearing S permanent bearing boxes C is the driving journaled therein and in which one end of shaft D with a pulley D fixed at one end the shafts is journaled, said cam member 40 having belted connection D with a driving S having an integral arm S projecting wheel D of an engine, whereby power may therefrom which pivotally connected to a be continuously transmitted to said shaft D. rod S which in turn is pivotally connected Fixed to the shaft D is a circiunferentially at S to the short arm of the lever S A grooved pulley E about which preferably is pinion wheel, designated by letter T and 45 a. strip E of leather or other suitable fibrous shown in dotted lines in Fig. l. is fixed to material, forming a friction surface. A the shaft S and is adapted to mesh with the shaft F is mounted in a suitable boxing F gear wheel H, while a. frictionally driven upon the upright beams B and a drum F is pulley 'l," is also fixed to the shaft. S and is fixed to the shaft F as is also a gear wheel adapted to receive power by contact with the 50 H. A drill operating cable I winds about driving wheel D.

the drum F and is adapted to pass about a h'lounted upon the brace beams A of the pulley K mounted upon a shaft K and frame are the boxings X and X, in the which is 'journaled in suitable boxings K former of which one end of the shaft X is which. are fastened upon the tilting beams journaled and upon which the drum X is 55 L,-illustrated clearly in Fig. 2 of the drawmounted, while the other boxing X carries a rocking eccentric boxing X in which one ings, which beams are pivotally mounted end of the shaft X is journaled, and a pulley WV is fixed to the shaft X and is driven by frictional contact with the grooved circumference of the driving pulley E. A cable Y, designed to operate a sand pump, not shown, winds about the drum X and is designed to pass about a pulley, not shown, upon one of the beams of the frame. A rod Z is pivotally connected to the arm X which projects from the eccentric boxing X and is connected at its other end to the rivet S carried by the lever S The operation of my invention will be readily understood and is as follows Power is adapted to be continually communicated to the driving wheel E from the engine through the belted connection shown. lVhen it is desired to cause the well drilling cable to be actuated, the lever R may be manipulated to cause the pinion wheel R which is driven by the shaft J which in turn is operated by the friction pulley It engaging the driving wheel, to mesh with the gear wheel 0 causing the shaft 0 to rot-ate and with it the eccentric pinion O which is in mesh with the eccentrically mounted pinion O, which will cause a rocking movement to be imparted to the beams L, thereby causing an intermittent jerking or pulling down movement upon the cable which carries the drill. The raising and lowering of the cable I may be effected by the manipulation of the lever S which will cause the pinion wheel T to intermesh with the gear wheel H, thereby causing the latter and the drum F 2 to rotate and wind up the cable I thereon.

In the event of it being desired to cause the cable Y to wind upon the drum X to operate the sand pump, the manipulation of the lever S will cause the pulley W to be thrown frictionally into contact with the driving wheel E and simultaneously with the same movement the pinion T will be thrown out of mesh with the gear wheel H.

hat I claim to be new is 1. A well drilling apparatus comprising a frame having a driving pulley mounted thereon, a suitably journaled shaft, a drum mounted thereon, tilting beams, a pulley journaled at one end thereof, a cable passing about said pulley and winding upon the drum, an eccentrically mounted gear j0urnaled upon said beams, an eccentrically ing about said pulley and winding upon the drum, an eccentrically mounted gear journaled upon said beams, an eccentrically mounted driving pinion meshing with said gear and mounted upon the frame, a shaft journaled at one end in a fixed bearing upon the frame and an eccentric boxing in which its other end is mounted, a pinion upon the shaft which is journaled in an eccentric bearing and a gear wheel adapted to mesh therewith and communicate motion to the eccentrically mounted driving pinion, a frietionally driven pulley rotating with the pinion carrying the shaft, and means for shifting said eccentric boxing, as set forth.

3. A well drilling apparatus comprising a. frame having a driving pulley mounted thereon, a suitably journaled shaft, a drum mounted thereon, tilting beams, a pulley join-naled at one end thereof, a cable passing about said pulley and winding upon the drum, an eccentrically mounted gear journaled upon said beams, an eccentrically mounted driving pinion meshing with said gear and mounted upon the frame, a shaft jo-urnaled at one end in a fixed bearing upon the frame and an eccentric boxing in which its other end is mounted, a pinion upon the shaft which is jo-urna led in an eccentric bearing and a gear wheel adapted to mesh therewith and communicate mot-ion to the eccentrically mounted driving pinion, a fric tionally driven pulley rotating with the pinion carrying the shaft, an arm projecting from the eccentrically mounted boxing, a pivotal lever and connections between the same and said arm, as set forth.

In testimony w iereof I hereunto affix my signature in presence of two witnesses.
